Question

In addition to SNPs, humans exhibit copy-number polymorphisms (CNPs), which result from relatively large deletions or insertions of certain segments of the genome. One study showed that individuals differed by 11 CNPs with an average length of 465 kb. Calculate the fraction of the human genome represented by copy-number variants.

Short answer

The fraction represented by the copy number variants is around 12% of the human genome.

Step-by-step solution

Gene fraction representing copy number polymorphism

Human genome has single nucleotide polymorphism as well as copy number polymorphism.

Explanantion

Individuals differed by 11 CNPs with an average length of 465 kb.Taking into consideration the total number of genes in human DNA as approximately 30,000 . So the fraction representing the CNPs is 12% of the human genome.
